This is wonderfully covered in Alan
McRobie's New Zealand Electoral Atlas.In 1862 the House of Representatives making two
adjustments to Otagos province's representation. The text explains the changes and shows
how the boundaries were redrawn.The New Zealand Electoral Atlas is an excellent book
which I believe is still available and is a great addition to any serious N Z
genealogist's library. AND no I have no financial interest in the book nor do I know the
author. I just admire such careful and scholarly work

The subject of "miners' right to vote" is quite
well covered in Tony Simpson's book "The Immigrants".Basically we followed the
lead of the Victorian Govt in Australiia who after the Eureka Stockade granted miners a
licence at 1 pound per year and the right to vote on production of this licence. In NZ the
"Miners Franchise Act" was apparently passed in 1860 giving NZ miners the right
to vote on production of their miners' licence. There is quite a lot more detail in Tony
Simpson's book on pages 148 - 50.
